ProfessorOh, absolutely! You can draw a circle with a circumference of 33cm. Just remember, the circumference is the distance around the circle, so you can use a compass or a circular object with a radius of about 5.25cm to draw it. Just take your time, enjoy the process, and let your creativity flow onto the page.

Why is not possible to draw a circle with a circumference of 100cm?
It is possible. Just keep the drawing instrument 15.915 cm from a set point (the circle's center).
Is it possible to draw a circle of negative radius?
Radii are always positive. No, it is not possible to draw a circle with negative radius.
How do you find a chord of a circle with diameter 26?
There are an infinite number of possible chords in anycircle, regardless of its diameter. A chord is a line segment with its endpoints on the curve (circumference) of the circle. You can draw those all day and never draw the same one twice.
Divide a circle into 12 equal parts?
Use a pair of compasses to draw a circle. Without changing the compasses, place the point of the compasses on the circumference and draw a small arc such that it intersects the circumference. Put the point on this intersection and repeat until you have 6 equally spaced "intersections". Select 2 adjacent intersections and, from each of them, draw an arc outside the circumference such that the 2 arcs intersect. Draw a line from this intersection to the centre of the circle. This line intersects the circumference halfway between the adjacent points. With the compasses set to the original radius of the circle (it's better to leave them fixed at this throughout!) place the compasses' point on the intersection of the straight line and the circumference then draw a series of arcs, as you did originally. These will complete the division by 12
What is an arc in math?
An arc is a portion of the circumference of a circle, and the circumference of a circle is the distance round a circle. So an arc looks like a semicircle, it is part of the circumference. Arcs are often used in constructions, for example if you were asked to draw an angle of 60 degrees without a protractor you would draw arcs following a special method. Arcs are drawn using a tool called a pair of compasses.
